Very useful parameter when selecting an electric vehicle is the maximum slope overcome. Here the explanations on the types of ascents and type of vehicles to be used.

To calculate a percent slope simply you apply the following formula:

percent slope

If I cover one meter and I rise 30 cm the percentage of slope is 30%. 

In practice how to do?
Just take a one meter shaft, a spirit level and a plumb line. Put the rule horizontally checking with the level, and then write down how long is the plumb wire, this distance will be the searched percentage.

Make attention don't confuse percentage and degrees. A 100% slope is a 45° slope... (try with the just explained method!)

WARNING: Gradeability for vehicles is measured in percentage, and it differs from the slope in degrees, for example, a 100% slope is a  45 degrees slope. The slope in percent and the slope in degrees are DIFFERENT.

Is maximum slope the only important parameter?
No, we must also consider how long it's such an uphill climb to overcome a 10-15 meter such as a ramp to the garage or in hospitals is very different from facing a climb of a hill.


Vehicles and slopes
: very often our customer ask us what is the best vehicle that best fits depending on the terrain and climbs to be tackled, we here a brief summary:
slope - electric vehicles test - ALKE - waste collection vehicles

slope - electric vehicles test - ALKE ATX 200E - waste collection vehicles

ParametersDescription
Garage rampAll Alkè ATX210E and ATX 110E electric vehicles have no problem, because they are optimized for that situation.
Slope of an embankmentAn electric vehicle is able to deal with departures from standstill uphill smoothly
Dunes slopeFor sandy soils must have an electric vehicle or 110E ATX ATX210E with trim and off road kit "Alkè sand."
Hilly paths uphill 400mt.In this case it becomes necessary to have an electric vehicle ATX 110E or ATX 210E with HP25 power kit, and we must analyze the length and terrain characteristics.
Dirt up and downFor the dirt road you must have an electric vehicle ATX 110E or 210E with SUV attitude and you have to go and analyze the slope of the most insidious that should not be above 30% if it is between 30% and 40% becomes need the kit HP25.
Dirt track - up to 46 % gradientIn this case you need the vehicles Alkè XT 420E
Off Road - up to 100% gradientIn this case the best vehicle is an 4x4.


 

Table: Recommendations to better tackle the slope with different road surfaces. Do not underestimate these parameters.

SlopeDescription
Slope asphaltThis slope is the easiest to address because the power required is constant.
Slope on dirt with holesThe presence of holes increases the slope so if you stop inside a hole is required in the event missed departure to go back.
Ascent stepsThe steps increase the slope of the hill so if you are greater than 7 cm. necessary to construct the tracks so that the slope is constant.
Ascent steps with hairpinThe hairpin is the critical point of a climb as it is missing a run and also it has the maximum slope, so it is here that we must calculate the slope of the hill.
